Be yitlnmwn um LJAMES M; Monet-mln, fthe city. of `Brook] yn,`c'onl`1 ty oi' Kings, Stateinf New York, `have inventedja newnnd'useful Improvement in Unions y for Connecting Steam,wGas,`nnd other Pipes; and Ido `herebydeclare the; following-to beafulholear, andex- ,factdescription thereofto enable others skilled in the :art towhich the saidfinvention appertnins to ceu-ryV it into effect, reference being had to the accompanying drawing forming a` part of thisspecicatioD, in

In the drawing` "-1 *5^ l, The lctterA` represents female screw `dfaudfcircularllugs al, which nut` `unites 4 the" nut formedgwth the The-outer ends. b bf of thel unions AB ,and O "are "threaded on theirinnei' surfacesyso as to screwthe :ends ofthe threaded pipesli F3 merma into niemn A, has

l `formed on its face n. series of concentric tongues Vor u n ridges, E E', while the fece of Athe part() is.formedA `withfone or more grooves, into which ispermanently carry the pipes F F in such a. manner that th packl ing D D -in the'faceof the partO can be brought to `b ea'r and rest upon the concentriotongues or ridges E 'E'4 formed upon 'the face of the part B, whereby aperfectlytight joint or connection is easily and reliably produced.

The elastic facing or packing is permanently fastenedpto the face ot'- the unions by the vulcanizing process, or it may simply be placed in the "concentric grooves. '1

It is thus readily seen", thatthe ends of the pipe are unitedtogether, the other ends -of the pipe being already fastened, and cannot be turned.

l The advantage of these unions over the ordinary onesare that they are complete in themselves, always `ready for use when'r'equired, and there is no delay in connectingpipes by stopping to out and shape the pieces forpackng, as is necessary in other unions. t Having thus described my invention, l

What I claimv as new, and 'desire `to secure by Letters-Patent, isf'- The improved unions herein shown,'cousistiug of `the parts Bland 0Vformeiwith the inner threaded i' surfaces 4b b', and concentric ridges E E', and groove to receive the packing D D', in combination withV the threadednut A and pipes F F', the whole `constructed and operating as herein shown and described, for the l purpose set forth. l y
